The BRS thermostat lets the cooling system get a head start on the temperature all of the car’s systems are creating. The thermostat may cause a check engine light on a street driven car but it doesn’t affect how the car runs. Because of this we only recommend running the thermostat on cars that are mostly driven on the track.
Now we are going to remove the OEM oil cooler.
We remove the hoses and unbolt it from the engine case.
The cooler is lifted free.
Here is the stock cooler size for the engine and PDK fluid comparted to the large BRS coolers. The difference in size is huge! The BRS units have more than twice the capacity and are about the same size as the units found on the 500 hp GT3RS or 991.2 Cup Cars.
To install the PDK cooler we removed this bracket.

Do you know if both the BRS side mount cooler and the BGB cooler can be installed? Or do they both cool the same (clutch?) oil?
One cools the tranny and the other the differential. Since we are not running a LSD yet, I didn’t think we needed a cooler after talking to guys who race these cars.
If you were to run an LSD, which LSD, and what cooler would you be exploring to use?
Probably a Setrab with an electric pump.
How did the intake manifold fit? It doesn’t seem like there is enough room for the larger oil heat exchanger. Also how far does the oil pan hang down front to rear?
Perfectly.
Great series on a great car. I’d love to see some before and after temperature data of the engine oil, pdk, and coolant system after all this work. I’d like to lower my own temperatures but it’s hard to know how much needs to be done to achieve reasonable temperatures.
We didn’t take any before but these cars are known to go into limp mode in just a few laps with a fast driver due to the PDK overheating. Ford Factory driver, Billy Johnson drove the car for a full session on a hot day with no issues, tuning a 1:57 at Buttonwillow.
Now that it’s been a couple years, how is the cooling on the 987. 2 working out on the track? I’m considering buying a 987.2 Cayman S and my only major concerns are the cooling and reliability of the PDK on the track (which I feel is related to keeping it cool)
Very well, is good even in hot weather.
